ABSTRACT:
Lawn rakes and rake attachments, and methods of use are disclosed. An open top, open front receptacle is disposed on the raking platform for use with a push raking operation wherein the rake teeth are turned upwardly. The rake generally slides under lawn debris such as leaves, so the debris rides over the upstanding teeth and onto the main portions of the teeth, onto the rake body platform and against the rear wall of the receptacle. With continued pushing, a deeper pile of debris collects on the rake and accumulates ahead of the rake. The push raking operation requires less energy and less dexterity, to move a given amount of leaves, than a conventional pull raking operation. Accordingly, some elderly, injured, and handicapped persons who cannot do pull-raking work, can now clean up their lawns using the apparatus and methods of the subject invention.
